AutoPlay
The 744T can be set to play back all valid audio fi les in a directory. Files will play back in their order
in the directory. Autoplay can be set with the following options:
• Disabled – auto playback is off
• Play all – all fi les in the directory will play, then stop when all fi les have been played
• Repeat one – the selected fi le will play back, then continue until
• Repeat all – all fi les in the directory will play in succession, then repeat until stopped by the
user
Storage Medium – Internal Drive
The 744T’s internal hard disk drive is the 744T’s primary storage medium. The large capacity and
fast data read/write speeds of hard drives are a perfect choice when long form, high data rate
recording is performed. This is a good balance of speed, reliability, noise performance, and current
draw. Higher speed drives may be used with the 744T, however they will not signifi cantly improve
performance. They will slightly increase transfer throughput with the penalty of increased current
draw and reduced battery run time.
Formatting
The drive installed in the 744T is formatted at the factory as a single-partition FAT32 volume. If a
drive with multiple partitions is installed, the 744T will only “see” the primary partion. The 744T can
only address one partition.
As a matter of routine maintenance, periodic re-formatting of the 744T hard drive is recommended.
Formatting the hard drive rebuilds the FAT (fi le allocation table) and erases any audio or other data
fi les present on the medium. This reduces possibility of directory corruption.
Be certain that all fi les on the 744T drive have been backed up to another media before formatting. Once
formatted, all data on the drive will be erased.
To format the 744T internal hard drive:
1. Ensure that all data on the hard drive has been copied or is no longer needed.
2. Press the Menu key.
3. Use the Multi-Function Controller to scroll to In HDD: (Erase).
4. Press the controller button to begin formatting.
5. Press the controller once more to confi rm the operation.
Formatting the 744T hard drive can take up to 30 seconds. When the format is completed, the 744T
will create a fresh menu hierarchy, including the daily folder, if selected. Once you exit back to the
main screen the 744T is ready for recording.
Drive Repair
Included in the software for the 744T is a basic drive repair utility. The utility is similar to Windows
“Scandisk” and will check for fi le system integrity, recover lost cluster-chains, fi x or recover dam-
aged fi le allocation tables (FAT), and repair corrupted WAV fi les. This utility should be run after
improper media removal, or in the event of a write error during recording.
